Android APP with timer (millisec accuracy) and DB functions + BT control option

Please note: I started a project about 1 month ago with a quite similar name, but on the basis of the feedbacks I felt the need to clarify the description. Since I could not revise it, I created a new one with a slightly enlarged functionality.


I would like to have a stopwatch APP for Android similar to this:

[login to view URL]

Some screens of the application I considered to be important, are attached. See the 'Screen Design (draft).png' file. It also contains essential information about how the application should work. The size and placement of buttons, proportions to each other, format of values, transparency and clarity of the user interface is necessary.

The APP button functions should be remotely controlled by a universal Bluetooth device, something like this: [login to view URL]

I thought the left an right side buttons on the phone display should be in line with the 'Previous song'

and 'Next song' buttons of the BT device (VOL-, and VOL+ is also acceptable).

After the AUTO SAVING function, the APP should store the values into a database.

One row should look like this (see the example of the png file):

Right; 2.109; 1.264; 1,237; 0,722; 2-0

The DB may contain 500+ of these rows:

Left/Right information + 10-12 time values in milliseconds (no larger than 4000 ms each) + 0-0 format 1st-2nd value.

The export/import option of this DB is also required (the ability to send is good, but not enough on its own).

At the end of the project I need the source code of the application (clean code please! :)

There is a good chance that later - based on the usage, and experience - I would like to expand and modify it.

So: if you are interested in this project, please keep in touch!
